Beta releases are intended to give the wider community the opportunityto test new features and bug fixes and to prepare their projects tosupport the new feature release. We strongly encourage maintainers ofthird-party Python projects to test with 3.6 during the beta phase andreport issues found to bugs.python.org as soon as possible. While therelease is feature complete entering the beta phase, it is possible thatfeatures may be modified or, in rare cases, deleted up until the startof the release candidate phase (2016-12-05). Our goal is have no changesafter rc1. To achieve that, it will be extremely important to get asmuch exposure for 3.6 as possible during the beta phase. Please keep inmind that this is a preview release and its use is not recommended forproduction environments

The next planned release of Python 3.6 will be 3.6.0b3, currentlyscheduled for 2016-10-31. More information about the release schedulecan be found here:
